TAKE-UPAND LET-OFF'MECHANISM Foe LOQMS- SPECIFICATION forming part ofLetters Patent No. 246,714, dated September 6, 18 81.

7 Application filed MarchS, 1881. (No model.)

-'To all whom it may concern:

Be it known that we, WILLIAMA. BRAMALL and CHARLES R. INNES, of Chester,in the county of Delaware and State of Pennsylvania, have invented a newand Improved Take- Up and Let-01f Mechanism forLooms, of which thefollowing is a fnll,clear, and exact description.

The object of our invention is to operate the yarn-beam in It oms byconnections from the take-up mechanism, in order to provide for lettingofl the yarn uniformly. l

Our invention consists in a sliding stand fitted for movement to andfrom the yarn-beam and carrying friction-rollers that are geared to thetake-up mechanism. The stand rises as the yarn-beam diminishes in size,so that the friction-rollers bear constantly on the yarn.

' In the accompanying drawings, formingpart of this specification,Figure 1 is a rear elevation, partially broken, of a loom containing myimproved devices. Fig. 2 is a side elevation, and Fig. 3 is a verticalcross-section, of the same;

Similar letters of reference indicate corresponding parts.

The loom shown is of ordinary construction.

a. is the yarn-beam I), the whip-roll c c, the swords of the vibratinglay or batten. d is the roller on which the cloth is wound, and e lthetake-up roller, all asusual.

The clothpasses, from breast-beam f to the cloth-roller d beneath thesame, then up over roller 6, and down again to the cloth-roller. Theroller 0 is sanded, so that by its revolution it draws the cloth and atthe same time turns the cloth-roller and windsthe cloth thereon. On theend of take-up roller 6 is a gearwheel, g, meshing with a pinion, k,that is carried by a stud fixed on the loom-frame. On the same stud andattached to pinion his a ratchet-wheel, i, which is given a step-by-stepmotion by the devices next described and the take-up roller 0 therebymoved. 7

k is a lever, hung on a stud fixed on a side rail of the loom. l is apawl, hung on lever k and resting on ratchetwheel m is a pawl,

' hung on the fulcrum of lever is and engaging with wheel '5 to preventback movement of the same. n is an arm or tailpiece, fixed on thecontact with the yarn on beam a.

in lever It. With this construction lever is vibrated ,by the lay so asto turn ratchet wheel i;

At the back of the loom, and beneath yarn on the loom-frame, and rollers10 p,that havetheir spindles jourualedrin the forked ends of rods 0...The rollers 10 are thus sustained across the loom and between theflanges of the yarn- 6o beam.

Beneath the rollers 19 two levers, q q, are

hung on standards q, and have their shorter arms connected by a pin andslot withthe slide rods 0 to raise the 1 rods 0 and sustain rollers 12in contact with the yarn on beam at. The free ends of levers q act bytheir weight to raise the stand and retain the rollers pin The free endsof the levers are made in two pieces con nected by a set-screw passingthrough a slot in one piece, so that the levers can be adjusted inlength to vary the weight and leverage.

The spindles of rollers 12 carry gear-wheels r, that connect with anintermediate pinion, 1", that is hung on a stud between the forks of rod0, so that the rollers shall revolve together. mechanism, fitted withaworin,s,thaten gages with one wheel, r, and carrying at its other end abevel-pinion, t, that engages with a bevel-gear wheel t; Thisbevel-geart is on a shaft, a, driven by straight gearing from thespindle of take-up roller e. The shaft u is sustained by a bracket, 11,fixed on the loom-frame,on which bracket is hung a swing stud or box,10, that sustains this end of shaft 5. The end of shaft s'beneath beam ais stepped in abracket, w, fixed on one fork of rod 0.

The operation is as follows: At each forward movement of the lay pawlcmoves ratchet-wheel i the distance of one tooth or more,

and the roller 0 being thereby turned, the cloth 5 is theoperating-shaft of the'let-ofi" is takenup and wound on roller d. At the12 rise with the stand, thereby maintaining contact, andthe yarn isconsequently unwound at a uniform speed and to the same extent at eachmovement.

It will be seen that th'econnections from the take-up to the rollers 11are positive, so that, being once'adjusted, the motions are unvarying.

- The'mechanism can be applied to any loom for weaving any kind ofgoods. To regulate the movement; to the grade ot' filling, either.

coarse or fine, lever is is provided with aside armflc, on which is hunga movable weight, Z. This weight is used for moving the lever it forwardwhen fine goods are being made, in-

plaee of the positive connection by the tailpiece or arm n. Inthat casethe piece n will' be out of the slot and the'lever k behind it, so

i that as the lay moves forward the weight will cording to theadjustment of the tension of the cloth.

Having thus described ourinvention, what we claim as new. and desire tosecure by Letters Patent,is-

1. In aloom,the combinatiomwith the yarnbeam, of a. sliding tableprovided with means for supporting and making it movable to and fromsaid beam, the friction-rollers, the takeup mechanism, and the gearingconnecting the said take-up mechanism and friction-rollers, whereby thetable or stand rises as the yarn-beam diminishes in size and the rollerscontinue to press the yarn, as described.

2. Phe combination',in a loom,ot bevel-gearing it t, the take-up roller,shaft s,.worm s,

gearing r r, friction-'rollers p,slides o,balancing-levers q, andyarn-beam a, substantially as and for the purposes set forth. .7
